A few weeks ago, I learned about reflection, R = V + N*(V‧N). It works with velocity, and so far, I have no problems with it. Now I am expanding it further, by applying it to an object with a constant acceleration hitting towards a Pinball Bumper. That's right, a bumper with the ability to knock objects away with a higher velocity.

The problem for me is the object, O, instantly warped away from Bumper and constantly stays moving in a westward direction, instead of (moving eastward, slowing down, changing directions, speeding up westward, and repeat the cycle).

Does anyone know how to fix this? I hoped I have provided sufficient information. Thanks in advance.
